Objectives

After completion of this course each learner will have a good understanding of the protection principles used in over-current, frequency, distance and differential relays. The learner will have a working understanding of the OMICRON secondary test equipment hardware and the OMICRON Test Universe software. The learner will know how to run and update pre-prepared test templates for various kinds of protective relays.

Software session

The participants will be familiarised with the important aspects of the Test Universe software. Each learner will perform a number of tasks using the test software in the offline mode, i.e. with no CMC connected.

Practical session

The participants will have to apply the gained knowledge. Test stations with a test set each for a distance, a differential and an overcurrent relay are set up. The participants are divided into groups, which rotate through the different test stations performing a number of tasks at each station.
